How much grain can a cylinder of the radius 4inches and height of 11inches hold?

553.0 in³

Step-by-step explanation:

(please see attached for reference)

Assuming you are asked to find the volume,

the volume of the cylinder is given by

V = πr²h

where,

π=3.142

r = given as 4 inches

h = given as 11 inches

Substituting these values into the formula,

V = πr²h

V = 3.142 x 4² x 11

= 552.99

= 553.0 in³ (rounded to nearest tenth)

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
